Бывают иногда достаточно неприятные ситуации, when the operating system crashes. And to restore the required original disk. If that is not available, you can burn the image on a regular USB flash drive. But here's the problem - what to do when there is no boot from a flash drive in BIOS? Many users simply do not know what to do, and are lost in this matter. Let's try to dot all i's.
How to enable booting from a flash drive in BIOS the easiest method?
To set these options, firstyou should decide on exactly how the BIOS will be entered. The most common way is to use the keys Del, F2, F12, etc.
However, on the same Sony Vaio laptops accesscarried out using a special button ASSIST, made on the keyboard panel. On some laptops, access to the BIOS can only be obtained by calling the primary boot menu using the Esc key.
How in BIOS to set loading from the USB stick?Yes, very simple. After calling the system I / O, you need to go to the boot section (Boot). Here you need to find the boot priority string, which can have different names, depending on the BIOS developer and manufacturer (Boot Device Priority, Boot Sequence, etc.). In any case, something in this spirit will be present. But the point is not that.
What to do if there is no boot from a flash drive in BIOS?
It also happens that the boot flash drive is not recognized by the primary input / output system. With what it can be connected? There are usually several reasons for this:
- Incorrectly recorded image or installation distribution;
- incorrect loading;
- damage to the USB drive itself.
To ensure that all steps forboot from the flash drive is correct, you need to take a few steps. For the time being, the question of how to enable booting from a USB flash drive in the BIOS will be left in the background, and will turn to urgent problems.
Check in "Device Manager"
Let's start with the last item.When checking the device itself for its functionality, there may be two options: either it is faulty by itself, or is missing or the accompanying driver is incorrectly installed, which is responsible for recognizing the flash drive by the operating system.
With faults everything is clear.The device will just have to be replaced. But what to do when it is in working condition (at least, it is determined on another computer or laptop)? We need to check its functionality. And for this, in the simplest version, simply insert it into the appropriate USB port 2.0 / 3.0, and then call the standard “Device Manager” via the “Control Panel” or use the devmgmt command in the “Run” menu bar (Win + R).
Suppose that after inserting a USB flash drive into the portdetermined In the manager, it can either not be displayed, or displayed with a yellow icon, on which there is an exclamation mark. In the second case, everything is simple: you need to install or re-install the driver. It may well be that the system itself does not find a suitable driver, although it should do this automatically. But it mostly concerns non-standard devices. Flash drives like Transcend are usually recognized immediately.
If the device in the corresponding controller is notis displayed, there may also be two reasons: either the corresponding universal USB controller driver is not installed, or the port itself is faulty. Again, you should install the driver (the controller is indicated in yellow or not in the controller at all), or try to plug the USB flash drive into another port. It should be noted that if the device is designed exclusively for data transfer only with USB 3.0 support, it will not be detected when connected to the standard port 2.0.
Formatting USB device partitions
Let us leave aside the question of how to boot from a USB flash drive in BIOS, and proceed to the procedures, without which even writing an image to install the system on a device may be in vain.
Прежде всего, если устройство имеет проблемы в work or cannot be done with it, you should format it first. In this case, it is undesirable to do a quick clean up the table of contents, and it is better to make a full formatting. Only in this case the file system contained on it will ensure the correct transfer of data and their reading.
Such an operation is performed in the standard"Explorer". On the device, you just need to make a right click, and from the menu select the appropriate line. In the new window, be sure to remove the "bird" from the quick format line, and then activate the beginning of the process. Depending on the total volume, this can take a long time.
Creating a bootable distribution
If we consider the question of how in BIOSset the boot from the flash drive, even wider, you can not ignore the question of creating a boot image and transfer it to the drive. This can be done using the UltraISO utility or similar.
However, the source should beoriginal installation disk Windows. Actually, creating a disk image is not so difficult, so there’s no particular reason to dwell on this in detail. And if there is no boot from a flash drive in BIOS, then it all comes down to correctly transferring the image or the unpacked distribution files to the drive. Here you have to tinker a bit.
Carrier preparation
In case of using own fundseven after formatting with a USB device, a number of additional actions are required (it is assumed that the image has already been created from the original disk using the same UltraISO program or even 7-Zip, and the USB flash drive is in working condition and connected to a computer or laptop) .
First, we call the command line (cmd in the "Run" menu), necessarily on behalf of the system administrator. In the console that appears, enter the diskpart command and press the enter button.
After that use the list disk command, againhowever, followed by pressing the Enter key, after which we scan the available disks and remember the number of the USB device. You can use the diskmgmt.msc command entered in the Run menu to precisely check the USB drive number.
Now in the console you need to enter the select disk command and after the space indicate the number of the required disk. Next, the device should be cleaned from the contents with the clean command.
Следующим шагом станет создание первичного boot partition. This is done using the create partition primary command and then typing. After confirmation of a successful operation appears on the screen, use the select partition 1 command, then active (to activate the selected partition) and finally format fs = ntfs quick for formatting with the choice of the NTFS file system. If you need to create a FAT32 file system, use the same command format fs = fat32 quick.
The next step is to assign the device a name whenassign command (the name will be assigned automatically). Finally, enter exit and exit. Bootable USB device is ready for use. It remains only to correctly transfer the distribution files to it.
Transferring data to a USB flash drive
At this stage, no longer need to configure.We do not need BIOS for booting from a flash drive yet, but the 7-Zip program will be needed. In the simplest version, with its help, you can correctly copy the installation files to the media (roughly speaking, extract them from the image).
Run Zip File Manager utility fromStandard “Explorer”, then select the image of the installation distribution kit that was previously created or downloaded from the Internet, specify the USB flash drive as the target device and confirm the actions by pressing the OK button. At the end of the process, the media will be fully operational.
Launch download
А вот теперь переходим к вопросу о том, как install in the BIOS boot from the USB flash drive directly. We reboot the system and at the initial stage we press a key or a combination of keys to enter BIOS settings. This is usually Del, F2, F12 (for ASUS laptops, BIOS-boot from the USB flash drive is exactly like this), but other keys or combinations described above can be used. Depending on the manufacturer of the equipment, you may first need to bring up the main menu. This situation is typical for laptops like HP - booting from a flash drive (BIOS) is installed a little differently, although the operations themselves are very similar.
In the download section (Boot) look for item Boot DevicePriority and look at the line 1-st Boot Device. Pressing the PgDn key selects the device to be searched for, and then exits and saves the parameters (as a rule, this is done with the F10 key). This is followed by a reboot, and the installation starts automatically.
However, it’s not enough to know how to select boot fromflash drives. It is important to remember that the primary settings of the input / output system should be called up only when the USB device is connected before starting the computer or laptop. Otherwise, the flash drive is simply not defined.
How to fix the problem?
Now look at the situation when the deviceIt seems to be working, since all the above actions are supposedly performed correctly, but in fact, all the same, there is no boot from the USB flash drive in BIOS. What to do in this case?
Use all the same command line.Suppose that the USB device in the system is indicated by the letter F, and the optical drive is E. Now you need to register the command E: Bootbootsect.exe / nt60 F: (F - in our case, a flash drive, and E - the drive).
Alternative method
If this does not work, in turn enter the following:
F:
F:> cd boot
F: Bootbootsect.exe / nt60 F:
After that, everything will work as expected.
Compatibility issues
In case none of the above methodsIt does not help, first you should pay attention to the status of the drivers. In the most optimal variant, you can use programs like Driver Booster, which are able to update drivers automatically.
Если с ними все в порядке, причина может состоять that the user is trying to install a 32-bit system over a 64-bit one. In addition, the file system on the USB-drive and the installation distribution can also differ exactly the digit. Actually, the flash drive itself may not support USB 3.0 ports, in which it is included. Here you need to be very attentive.
Instead of the total
That, in fact, is all about howBIOS set download from flash drives. Of course, many users may have questions about the advisability of using their own system resources for preliminary actions, because automated programs make it much faster and easier. But here I would like to note that such knowledge is extremely important, and programs with failures in access to the Internet are also not always at hand.
But the prerequisite, as already understood,is a disk image that is created from the original or downloaded from the Internet. Without it, nowhere. It remains to add that attention should also be focused on the digit capacity of the installed system, since the 32-bit version over the 64-bit system will not be installed without formatting the system partition. This is due only to the fact that for OS versions 32 bits the FAT32 file system is required, and for 64-bit modifications - at least NTFS. And the flash drive itself must have the appropriate FAT or NTFS file systems, and not UDP, as is sometimes the case. As for the volume, 4 GB will be quite enough for any system, including even the tenth modification gaining popularity.
